Re: the Official Runway Distance thread

Only about 15hrs to date with the Jab. Phil the way I see it aft elevator
increases lift on the canard which transfers weight back onto the tail wheel
during rollout and that is what we want for steering. I have explained my
views on some of the 6 pack items and the reasons why and I hope no-one is
offended by that. I think my reasons are OK and I really do believe that it
is time to get a standard operating procedure sorted out for the reflexor.
I think I am not the only one to see a loss of elevator authority due to
flush aelerons. I am happy that the reflexor was not an issue with N870BM
and that may be because they were never flush but always reflexed to some
degree.. I have explained my own experience and will be able to report again
on elevator authority with flush aelerons on VHONQ. The sparrow strainers
have not been altered but I have been operating with more reflex than before
and I think that is probably the cause of the strained wrist. Stay tuned.

Peter. The elevator is at the wrong end of the craft to make the tail go
down. It has no effect on the downward force applied to the tail. This is
going to turn into a physics class and for some minute degree of force
differences there might be some small amount argued by some.

You are doing something right since you are flying in that Jabiru craft. I
can't knock success, but I still get a since that you absolutely have a
closed mind to the whole 6-pack contributions. In N870BM there was not any
setting that made the aircraft dangerous to fly. Aileron authority was
positive regardless of setting. It just made a lot more things possible and
definitely helped stick the tail wheel during landing rollout. Your comment
about holding elevator makes me think that your sparrow strainer setting
be a factor.

How many flight hours do you have on that Jab to-date?
